Activator

  "id": "MLC-T-CHM-000181",
  "term": "Activator",
  "field": "Chemistry",
  "definition": "A species that speeds up a reaction already promoted by a catalyst, without acting as the catalyst itself. It binds to a reactant or to the catalyst and raises the catalyst's effectiveness, for example by changing its shape or its electronic state. Kinetic methods of analysis exploit this effect: under fixed conditions the measured rate increase is proportional to the amount of activator present.",
